Strong induction examples and solutions

WebFor example, if you want to prove that every positive integer can be factored into primes, if you use ordinary induction you would have to first show that 1 can be factored into primes, and then you would show that if k can be factored into … WebJan 6, 2015 · Here is the entire example: Strong Induction example: Show that for all integers k ≥ 2, if P ( i) is true for all integers i from 2 through k, then P ( k + 1) is also true: Let k be any integer with k ≥ 2 and suppose that i is divisible by a prime number for all integers i from 2 through k. We must show that

What

WebThis means that strong induction allows us to assume n predicates are true, rather than just 1, when proving P(n+1) is true. For example, in ordinary induction, we must prove P(3) is true assuming P(2) is true. But in strong induction, we must prove P(3) is true assuming P(1) and P(2) are both true.

WebInduction problems Induction problems can be hard to find. Most texts only have a small number, not enough to give a student good practice at the method. Here are a collection of statements which can be proved by induction. Some are easy. A few are quite difficult. The difficult ones are marked with an asterisk.

Proof by strong induction Step 1. Demonstrate the base case: This is where you verify that P (k_0) P (k0) is true. In most cases, k_0=1. k0 = 1. Step 2. Prove the inductive step: This is where you assume that all of P (k_0) P (k0), P (k_0+1), P (k_0+2), \ldots, P (k) P (k0 +1),P (k0 +2),…,P (k) are true (our inductive hypothesis). buy tetracyclineWeb1 A geometrical example.
